Disregard this post it is in error!!!
Edited by stevens.The HISTORIAN BADGE is based on playing only the Original 16 battles. So other battles do not come into play in that calculationHowever,(this is my conjecture)the ADVANCED HISTORIAN badge will probably involve something of a certain number of ALL the scenarios played on a certain battle date and so you can always be working toward that goal, just in case that is the required goal.
